Police have arrested about 100 people in St. Paul during protests of the recent police killings of black men, including one outside Minnesota's capital city. Authorities say 21 St. Paul officers and six state troopers were hurt during the fracas late Saturday and early Sunday. St. Paul Mayor Chris Coleman and Police Chief Todd Axtell are condemning the violence. Axtell calls the pelting of officers with rocks, bottles and other objects "a disgrace." The Star Tribune reports about half the arrests came during a blockade of Interstate 94 in St. Paul. About 50 arrests were made early Sunday in another part of St. Paul. The interstate reopened early Sunday. The protest was among several demonstrations nationwide following the deaths of 32-year-old Philando Castile in suburban St. Paul and 37-year-old Alton Sterling in Baton Rouge, La.

Authorities in Baton Rouge say more than 100 people were jailed in connection with the Black Lives Matter protests held in the Louisiana city over the weekend. Among those arrested was DeRay Mckesson, who rose to prominence with the Black Lives Matter movement after the 2014 shooting death of Michael Brown in Ferguson.

San Antonio police say shots fired overnight near the department headquarters hit the building, but nobody was hurt. Chief William McManus says investigators are trying to determine whether the building was targeted Saturday night or if someone was randomly firing. Police detained one person for questioning after the man was seen running from the area. McManus says several shell casings were found in a nearby alley.

President Obama says protesters who attack police officers are doing a disservice to their cause. Obama also cautions that if protesters paint police with a broad brush, they could lose allies for their cause. At the same time, he says that when police organizations acknowledge there is a problem stemming from bias, it will contribute to solutions. Obama is cutting his first visit to Spain a day short.
